Well, I tend to look at things over my perspective. I am interested in new boats, or relatively new boats, and as many guys, I would change my boat after 10 or 15 years for more performant boat and a boat that give me no maintenance problem. Many sailors in Europe change boats each 4 (to 7) years.

For these ones, a well made cored hull would not mean any problem. Not for them not for the second buyer of that boat. You say that at a very long term (20 or 30 years) the hull would have more problems than a solid fiberglass hull? Yes I probably agree, but I don't care. Anyway at that stage the value of the boat would be a very small fraction of its initial price.

Paulo

Well

As i have drill a few holes in Jboats



That 4 MM on the left is the OUTER-SKIN and the nice thick one is the inner

The chunks on the far left are from a J160 that fell over and landed on a pile of OPEN jackstands

Having the quest to learn i went over and pull out the 50K core samples the stands had taken and i can assure you the outer skin on a BIG Jboat is NOT all that thick just thicker balsa

If a dirty bottom slows you down what do you think it does to your boat

Again, I say in cruising boat or performance cruising boat, why bother? And there is absolutely nothing wrong with grids and liners.

And as for you, T37 chef, my momma could be put on a Farr 40 and my kids could beat her in the Compaq. I can't help it if the guy didn't know how to sail!!!! Most of the people that can't sail buy Telstars. Maybe he was motoring to the Telstar dealer??

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Brian,

Because comparing two exactly equal boats, one with cored hulls, the other with solid fiberglass hull, the cored one would not only sail better as it would be a safer boat, with a far better overall stability. Progress is that. Builders make the boats, the best they can, for a given budget. If they can make a better boat, why should they make a worst one?

That's the same thing with injection and infusion technics. Why bother? Because with them they can make better sailing boats

Regards

Paulo

Hey Paulo, like I said, Catalina (I am just using them as an example) and I discussed this Friday. THeir reasoning was not cost, but to have solid glass under the waterline in the event of a hard grounding. They prefer the bulk. In a perfect world where no one hits anything, I see your argument and agree. But I run aground all the time and want solid glass below the water.

You made the case that it is a cost issue and I dissagree. Here are some other boats that use solid glass:

Taswell
Tayana
Hylas
Not sure, but I think Hallberg-Rassy?? I do know they also use a grid system and think it is a hand laid solid GRP.

It is a philisophical decision based upon use (in my opinion), not cost. However, coring is a more expensive process especially when using divinycell, etc. It is a better process for high performance. I just don't think it is the right process for all boats depending on intended use.

Again, just my opinion.

Brian

If you run aground the keel should touch, not the hull. If the hull touches you are really aground.
